So I tried using one but its too simple. What if the zombies dont spawn where they are suppose to? Will they? I need a plugin like Call Of MineCraft Zombies, but more advanced. For example I want their to be waves, and I want the zombies to be able to spawn at the correct locations. For example, I want them to spawn in the room area, and not around the map where the doors havent been open yet.
I don't think people will do this for free, and Bukkit's rules make it so you can't get paid work done on their forums. Try posting at www.spigotmc.org and I'm sure you could find some to hire!
Theres a plugin out there like this gimmie a minute to find it. Well, this was a bit fast anyways found it, http://dev.bukkit.org/bukkit-plugins/call-duty-zombies/ Enjoy! EDIT by Moderator: merged posts, please use the edit button instead of double posting.
He is allowed to "donate" for the plugin in the form of a "pledge", like Mojang did when they were very first starting. People got rewards for pledging money.
These kind of plugins costs over $125. If you want to play on COD Mc server here is the link to PMC Page: http://www.planetminecraft.com/server/swarm---zombies-cod/
